LATHE FOR FORMING COLLARS UPON VEHlCLE-AXLES.

srnorr'ronrrrorr forming part of Letters Patent No. 654,756, dated July31, 1900. Application filed than 12, not; Serial N6. ,259. (No model.)

To aZZ whom it may concern.-

. citizen of theUnitedStates, residing at Canton, in the county of Starkand State of Ohio,

have invented new and useful Improvements,

in Lathes for Forming Collars upon Vehicle- Axles, of which thefollowing is a specification.

My invention relates to improvements in lathes for forming projectingcollars upon vehicle-axles; and it consists in providing a lathe with aclutch mounted upon a lathehead to engage one end of the axle, astationary rest to support the other end of the axle, a slide-restmounted upon the ways of the lathe and carrying a tool-head and operatedby means of a rack and pinion, anda weighted driving-wheel, as will behereinafter more fully described and claimed.

In the accompanying drawings similar letters of reference refer tosimilar parts.

Figure 1 is a perspective view ofthe upper portion of a lathe, showingmy invention. iiigl i 2 is a top View of the same portion of the at e.

of the upper portion of thetool head or block.

the rim of the weighted driving-wheel.

A represents the ways of the lathe and 'and when the same shall havebeen cut to the may be of any of the Well-known forms.

B represents the slide-rest, upon which are mounted the tool-rests C andD, one of which,

0, has a lateral adjustment by means of the cross-feed c, which may beof any of the Wellknown forms. The tool-rest D is adaptedto. have afixed adjustment upon the slide-rest by means of the thumb-bolts c and cThe tool-heads E and F consist of two flat pieces of metal grooved toreceive thetool tobe' used, and to hold the same against displace ment Iprovide the thumb-bolts e and f,which pass through the upper plates andbear upon the tools. The: tool heads or plates are held in engagementwith each other and with the tool-rests by means ofLscrew-threaded boltspassing throughscrew threaded aper tures in the tool heads and rests.-To the under side of the slide-rest there is attached a rackb,extending its" entire length and meshing with a pinion 19', mounted on ashaft Fig. 3 is a detachedperspectivo view of the weighted driving-wheeland pinion. Fig. 4 is a perspective view of the under side h journaledin the ways and carrying upon its .outer'end 'a weighted drive-wheel 12to which there is attached a strap b carrying the weights b G' is thelathe-head, which may-be of any of the well-known forms, upon the innerend of which is mounted a clutch 9, adapted to gripthe axle.

H is the inner supporting rack or bearing for the axle and may be madeof any desired form which will permit of the revolving of the axlethereongbut I have shown it consisting of. a forwardly-projectingbracket carrying ahinged plate It, mounted thereon and adapted to belocked in engagement therewith by means of the catch h. The cutting-toole is formed so as to cutthe annular groove in the axle, forming theproject ing sleeve or sand-bar, while the tool f is shaped so as to acteither as a stop or to cut the outer projecting edges of the sleeve.

In operation the cutting-tool andstop hav= ing beenmounted in thetool-head, the axle having been securely gripped by the clutch in thelathe-head, and the other end resting in the supporting-bracket, themachinery is started, when the weighted driving-wheel, rack, and pinionwill gradually carry the tool forward and against the axle, and arevolving of the same will cause the tool to em gage and cut the annulargroove in the axle,

desired depth the outer edge of the project- 'ing sleeve will come incontact with the stop f and the operation is completed and the axleremoved from the machine.

It will be observed that by the employment of this device a largenumberof like machines can be operated by one employee, the machine ispractically self-controlled, and the operation of turning or cutting isautomatically stopped, thus preventing any injury to 'the piece operatedupon by lack of attention from the operator. j p, Having thus fullydescribed my invention, what I desire to secure and claim by IijettersPatent is- The combination in a lathe, of a bed-plate with a revolvinglathe-head mounted upon a stationary supportingbracket, alongitudinally-adj ustable slide-rest carrying laterallyadjustable toolrests, and means for engaging the toois therewith, a rack aiataehed tothe my hand in the'presence of two subscribing I under side'of theslide-rest, a pinion meshing Witnesses.

therewith m'oiinted upon a shaft jbufnaled in the was and. carrying aweighted drive- J OBERMIER" '5 wheel, substantially as described andfonthe Witnesses:
